Overall, this place is highly recommended for those traveling in large groups (this apartment can fit up to 10 people comfortably). It is situated in a quiet area but easily accessible as it is nearby the Ari BTS station. There is a 7-Eleven nearby (1 min walk) which is super convenient for you to get groceries. The only drawback is that there is only 1 toilet in the apartment (there is an additional 1 on the Ground floor), so please plan your time accordingly if you are in a large group. There was a slight unpleasant odor in the toilet, which is probably coming from the plumbing/pipes, however it is tolerable.
Thank you JP for hosting us, this apartment will definitely be in our consideration the next time we visit BKK.
